Abstract

The invention discloses a main iron runner pouring material. The pouring material comprises alumina, brown aluminum oxide, SiC, modified nano carbon powder, SiO2 micropowder, calcium aluminate cement, alpha-Al2O3 micropowder, explosion-proof fiber, metal silicon powder, sodium tripolyphosphate and AL(OH)3 and Mg(OH)2 composite sol suspension. In the invention, the AL(OH)3 and Mg(OH)2 composite sol suspension is used as a nano ceramic binding agent and directly added into a mixture and forms a spinel nano structure substrate by in situ synthesis reaction to obtain the nano AL2O3 and MgO composite oxide ceramic combined main iron runner pouring material disclosed by the invention; after carrying out the secondary spinel synthesis reaction, densification is generated along with expansion under constraint, and thereby, macro-and-micro structure improvement, performance improvement and durability enhancement are obtained, and the main iron runner pouring material with high erosion resistance and infiltrating resistance, scour resistance, high thermal shock resistant stability and large iron flux is prepared.

Description

A kind of main iron hook mould material
Technical field
The present invention relates to refractory castable.
Background technology
Existing main iron hook mould material is common AL 2O 3-SiC-C matter mould material, but the general common AL that gets 2O 3-SiC-C matter main iron hook mould material is at 2500m 3Use on the blast furnace, disposable iron influx is at 120,000 tons.Along with strengthening smelting, the demand that improves output becomes increasingly conspicuous, and main iron hook requires the requirement of disposable iron influx also more and more stricter, and iron influx is not ideal enough.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of iron influx ideal main iron hook mould material more.Main iron hook mould material of the present invention is at 2500m 3Use on the blast furnace, disposable iron influx is more than 170,000 tons.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of main iron hook mould material is characterized in that: described mould material is by alumina, brown corundum, SiC, modified Nano carbon dust, SiO 2Micro mist, aluminous cement, α-Al 2O 3Micro mist, explosion-proof fiber, metallic silicon power, tripoly phosphate sodium STPP, AL (OH) 3And Mg (OH) 2Complex sol suspension is formed.
Preferably, the weight percent of each component is an alumina 5%~10% in the described mould material; Palm fibre corundum 50%~60%; SiC10%~15%; Modified Nano carbon dust 3%~5%; SiO 2Micro mist 3%~6%; Aluminous cement 2%~5%; α-Al 2O 3Micro mist 5%~10%; Explosion-proof fiber 0.02%~0.05%; Metallic silicon power 0.5%~1.5%; Tripoly phosphate sodium STPP 0.1%~0.5%; AL (OH) 3And Mg (OH) 2Complex sol suspension 5%~5.5%.
